One way that noise can permanently damage your hearing is by a single brief exposure to a high noise level, such as a firecracker going off near your ear. But hearing damage can also occur gradually at much lower levels of noise, if there is enough exposure over time. To protect your hearing, you’ll want to limit your exposure to these moderately high noise levels and give your ears a chance to recover after any period of noise exposure.
